Biology and Biological Control of
Established Invasive Plants in

Saturday October 18 - Brookfield Conference, Room #1
Crowne Plaza Hotel, Ottawa - start at 8:00 AM


Our principal objectives are to raise the profile of invasive plants and their biocontrol programs in Canada and enable networking to facilitate the management of established invasive plants in Canada. In this symposium we will start with introductory talks on 1) aspects that make plants invasive in Canada and 2) the background for invasive plant biocontrol in Canada, detailing some of the biocontrol success stories. These are followed with presentations on four invasive plants of interest; first discussing aspects of their invasion biology and ecology and then considering what is happening with their biocontrol program. The invasive plants considered are at differing stages in the development of their biocontrol program. Garlic mustard has just had a petition submitted for the release of a biocontrol agent. Vincetoxicum, Knotweed and Phragmities are at earlier stages of development, such as the identification of suitable agents, host-range testing and impact screening.

The symposium is in advance of the Joint Annual Meeting of the Entomological Societies of Canada and Ontario in Ottawa Oct 19-22. It will be a research symposium however the talks will be targeted to a broad group interested in operational level programs. We are hopeful that research, field and policy people will attend and that links can be made between new research partners to improve the management of invasive plants.
